Fitbit Inspire HR not logging locations; fix by turning off battery "power saving"
I was logging commutes from the Fitbit into Strava, and wasn't getting any GPS data - or, oddly enough, just getting GPS at beginning and end of a trip or weirdly intermittently. The Fitbit app didn't complain about anything. Getting tired of this, starting to shop for a new smart... Continue reading

CDK Global runs a software-as-a-service platform that car dealers use to run their back offices. Their system has been down since mid June 2024 after a ransomware attack attributed to the BlackSuit ransomware gang.

maintaining continuity in the face of disappearing data
If you have a chat system that deletes its history regularly, and if you want to maintain some long-term memory that outlasts the history purge, and if you don't have blogs or wiki or any other sort of public place to put things; then you put together a regularly posted... Continue reading

Bike Every Park 2024: 102 in the books

Framework laptop with a RISC-V main board
File under "interesting, but not likely to purchase in this go-around". Framework makes nice, modular laptops. They are modular enough that you can swap out the main board, keep everything else, and keep on trucking. That's a good thing. Upgrades become a component swap rather than a complete new system....

Ten years of not needing Kubernetes in the home lab
I'm happy that Kubernetes has made it to 10 years old, but I'm also happy that my homelab has not yet presented itself with any Kubernetes-shaped projects. Mostly the home stuff has been Raspberry Pi shaped objects attached to radios and antennas, which means the technology of choice has been... Continue reading

900 mile status report
The e-bike that I bought last August just hit the 900 mile mark. I rode it to Dixboro today, about 45 minutes there by the short route, and an hour back via downtown. Some notes so that I remember them the next time I hit a milestone. There are no... Continue reading

the irony detector is broken
Google's shiny new AI powered results are sometimes terribly wrong, because the algorithm misinterprets satire or jokes as factual information. There doesn't seem to be any real problem with the automated summarization process per se, taking a text and transforming it into another text that's shorter. But the things it's... Continue reading

enormous pile of words
We systematically underestimate the difference between an enormous pile of words and a coherent extended narrative. You type and type and type and answer a bunch of questions and contribute your hot takes and all of that. Then you look at that word pile and think "gee, I wrote a... Continue reading

typing a reply into a little box, thinking better of it, deleting the post
Rather than post a reply to a thread I will start one here. It's always best to be at the top of the page. Never read the comments. Not everything that someone else types into a little rectangle deserves a reply, even if you have one handy. Networks that are... Continue reading

Hamvention 2024 trip report
A trip report from Hamvention 2024 while it's still fresh in the mind. The ARROW bus from Ann Arbor was a success thanks to AC8TO who stepped up as cruise director. It was nice not to have to drive. We assembled at 430a in Ann Arbor, and stopped in Toledo... Continue reading

ext2 filesystem deprecated in Linux 6.9 kernel
See for the commit message. "Ext2 users are advised to use ext4 driver to access their filesystem. The driver is fully compatible, supports filesystems without journal or extents, and also supports larger time stamps if the filesystem is created with at least 256 byte inodes." Continue reading

Stack Overflow
I didn't need that account anyway. Add "takeover by a large language model" as one more way for an online community to die, to go with "takeover by Nazis", "overrun by spammers", and "starved by previously generous advertisers". Continue reading

Fun things to do with radio that are "not real ham radio"
If you enjoy any of these parts of the hobby in the presence of a purist, you'll get the dismissive reply that these are "not real ham radio". * Digital voice modes. DMR, D-Star, YSF etc get rejected because they use the Internet to interconnect repeaters. * Packet radio, because... Continue reading

About this blog
I gave a talk at Penguicon 2024 about the Epochalypse (year 2038 bug). The discussion after the event made me think I should keep at this for at least some of the next 14 years, looking at timekeeping related issues. Mostly this is a clippings blog, with references back to... Continue reading

"Leap smear", Google Public NTP
From > Since 2008, instead of applying leap seconds to our servers using clock steps, we have "smeared" the extra second across the hours before and after each leap. The leap smear applies to all Google services, including all our APIs. A software library for managing this is "unsmear" which... Continue reading
